exposed. Press the gasket over the screw heads. Slip the
backing plate over the screw heads at the keyhole slots
and align with the gasket; tighten the two screws until
snug (do not over-tighten).
Mount the weatherproof cover to the backing plate as
shown in Fig. 23. Remove two slot fillers in the bottom of
the cover to permit service tool cords to exit the cover.
Check for full closing and latching.

Weatherproof Cover Installation
Non−powered type: This type requires the field
installation of a general−purpose 125−volt 15−A circuit
powered from a source elsewhere in the building. Observe
national and local codes when selecting wire size, fuse or
breaker requirements and disconnect switch size and
location. Route 125−v power supply conductors into the
bottom of the utility box containing the duplex receptacle.
Unit−powered type: A unit−mounted transformer is
factory−installed to stepdown the main power supply
voltage to the unit to 115−v at the duplex receptacle. This
option also includes a manual switch with fuse, located in
a utility box and mounted on a bracket behind the
convenience outlet; access is through the unit’s control
box access panel. See Fig. 22.
The primary leads to the convenience outlet transformer are
not factory−connected. Selection of primary power source is
a customer−option. If local codes permit, the transformer
primary leads can be connected at the line−side terminals on
the unit−mounted non−fused disconnect; this will provide
service power to the unit when the unit disconnect switch is
open. Other connection methods will result in the
convenience outlet circuit being de−energized when the unit
disconnect switch is open. See Fig. 24.
Using unit−mounted convenience outlets: Units with
unit−mounded convenience outlet circuits will often
require that two disconnects be opened to de−energize all
power to the unit. Treat all units as electrically energized
until the convenience outlet power is also checked and
de−energization is confirmed. Observe National Electrical
Code Article 210, Branch Circuits, for use of convenience
outlets.

Convenience Outlet Utilization Notice Label
Test the GFCI receptacle by pressing the TEST button on
the face of the receptacle to trip and open the receptacle.
Check for proper grounding wires and power line phasing
if the GFCI receptacle does not trip as required. Press the
RESET button to clear the tripped condition.
Factory Option Thru−Base Connections —
This service connection kit consists of a
1

2
−in electrical
bulkhead connector and a
3
/
4
−in electrical bulkhead
connector, all factory−installed in the embossed (raised)
section of the unit basepan in the condenser section. The
1
/
2
−in bulkhead connector enables the low−voltage control
wires to pass through the basepan. The
3
/
4
−in electrical
bulkhead connector allows the high−voltage power wires
to pass through the basepan. See Fig. 26.
